QUESTION: May I exercise appeal rights before OWCP and the Board at the same time regarding the same issue in a case?

ANSWER: No. When OWCP issues its decision, it provides a list of
appeal rights. Among those options is a right to appeal OWCP’s decision to
the Board. Please review these carefully before deciding which option to
pursue. You may exercise only one review option at a time. Exercising more
than one option at a time will delay development and adjudication of your
appeal before the Board.
